Abstract With the evolution of mobile communication networks, three-dimensional graphics applications and services are fast developing fields in mobile graphics and wireless networks. While the data size of 3D meshes is increasing, the available bandwidth of wireless networks and the weak resources of mobile devices have become relatively limited. The transmission of graphics multimedia over wireless networks is a bottleneck problem. In this paper, a novel mobile 3D graphics compression approach for progressive transmission over wireless networks is presented. By improving the progressive coding framework using reverse Butterfly Scheme, a new progressive mesh coding algorithm based on the reverse Modified Loop scheme is proposed. The dense triangle mesh is decomposed into the progressive mesh which consists of a base mesh and a series of displacement values. Then the progressive mesh is compressed by the embedded zerotree mesh coding. The proposed approach allows the data of 3D mesh to be transmitted over wireless network using TCP and UDP protocols respectively. It speeds up 3D graphics browsing on mobile devices as well as optimizes the data size of 3D mesh for progressive transmission.
